Display Panel Positioning Structure for Screw-Aligned Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display device assembly process is burdensome for workers due to the need for visual positioning of screw holes, leading to potential size increases when using protruded and recessed parts for positioning.
Innovation Solution
A display device design featuring a display panel with a recessed display-side positioning part and a device housing with a protruded housing-side positioning part, where the screw hole communicates with the through hole, allowing for secure screw fixation without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual positioning of through hole and screw hole is used for assembly, then assembly process is simple, but work burden on worker increases
Solution Approach 1:
The positioning parts are designed to automatically guide and align the display panel with the device housing during assembly. The protruded positioning part on one component fits into the recessed positioning part on the other component, creating self-aligning features that eliminate the need for visual positioning by workers. This self-service mechanism reduces assembly complexity while simultaneously reducing work burden.
2Manufacturing precision
If protruded part and recessed part are added for positioning, then positioning accuracy improves, but device size increases
Solution Approach 1:
Instead of adding large positioning structures throughout the device, the patent applies positioning parts only at specific localized areas where alignment is needed. The protruded and recessed positioning parts are concentrated at the interface between the display panel and device housing, providing precise positioning without increasing the overall device volume. This localized approach maintains positioning accuracy while minimizing size increase.
3Strength
If through hole and screw hole are separately positioned, then screw fixation is achieved, but assembly difficulty increases
Solution Approach 1:
The patent combines the positioning function and screw fixation function into an integrated structure. The positioning parts are designed such that when the protruded part fits into the recessed part, the through hole and screw hole are automatically aligned. This merging of positioning and fixation functions allows workers to achieve both accurate alignment and secure screw fixation in a single assembly operation, reducing assembly difficulty while maintaining fixation strength.

AI summary
A display device includes a display panel that includes a first hole and a device housing that is configured such that the display panel is fastened and fixed to the device housing by a screw passed through the first hole and screwed into the screw hole. The display panel includes a display-side positioning part which is configured to fit to a portion of the device housing to perform positioning of the display panel with respect to the device housing and which includes the first hole, and the device housing includes a housing-side positioning part which is configured to fit to the display-side positioning part to perform the positioning and which includes a second hole formed so as to communicate with the first hole when the housing-side positioning part is fitted to the display-side positioning part.
